When this player is activated, they can declare a Stab Special Action; there is no limit to the number of players that can declare this Special Action each Turn.
When this player performs a Stab Special Action, select a Standing opposition player adjacent to this player and make an Armour Roll for the selected player. This Armour Roll cannot be modified in any way. If the player's Armour is broken, make an Injury Roll for them, otherwise nothing happens.
This player may use the Stab Special Action to replace the Block Action made as part of a Blitz Action if they wish, though their activation will still end as soon as they have performed the Stab Special Action.
